Cleaning and sanitizing system

Abstract

A high pressure water stream ( 14 ) is discharged onto a surface to be cleaned. An ozone/water stream ( 16 ) is discharged on the same surface for sanitizing the surface. The high pressure water and ozone/water streams ( 14, 16 ) are discharged simultaneously along closely adjacent paths that are either parallel (FIG. 3 ) or concentric (FIG. 2 ). The water pressure is at least about 100 p.s.i. and is preferably between 100 p.s.i. and 1000 p.s.i. The nozzles that discharge the streams ( 14, 16 ) may be movable relative to the object(s) that receives the high pressure water and ozone/water (FIG. 1 ) Or, they may be fixed and the object may be movable relative to them (FIG. 4 )

1. A method of cleaning an object, comprising providing a hand-held spraying device:
 directing a first stream of high pressure water from the hand-held spraying device toward the object; and 
 directing a second stream of ozone/water from the hand-held spraying device toward the object; wherein
 the steps of directing the first stream of high pressure water and directing the second stream of ozone/water are accomplished simultaneously. 
 
 
     
     
       2. The method of  claim 1 , wherein the first stream of high pressure water and the second stream of ozone/water are substantially parallel to one another. 
     
     
       3. The method of  claim 1 , wherein the first stream of high pressure water is adjacent to the second stream of ozone/water without admixing the ozone to the stream of high pressure water for a substantial distance.
